My observation is that speech recognition people do not really care about the difference between phones and phonemes. But linguists are really splitting hair. For me this separation always seemed artificial. The phoneme is an abstract notion cleaned from any acoustical correlate. I think it was invented in order to detach phonology from phonetics. But the notion of phoneme is at least well-defined. Phones are also a kind of abstract classes over the sound items, but I could never find any definition in any phonetics book... > So what's "the truth" here? Can computers create and/or recognise phomemes .. Oh, I also always in trouble with this. Should I say "phone recognition" or "phoneme recognition"? For example, if I had a software that could tell the species of animals, is it an animal recognizer or a species recognizer? The problem is that the word "recognition" inherently contains a mapping of a data item to an abstract class. So it does not deal with any of the sets but with the mapping between them.
